"He was on time. He got the quote to us when he said he would. He rebuilt the bathroom shower (and a few extra requests) in the promised time frame. It looks amazing! He is as friendly a person as there is. R&R was a great find for us! We'll call him for EVERY repair, install, or upgrade that we need."

"We came home from vacation to very stormy weather.  We found that our garage wall and top corner of the ceiling where the garage meets the house was WET.  We looked for someone on Angie's List to provide us with an estimate on repairing whatever damage might be up there causing this problem.  Due to three top-notch reviews, we called T&T Construction on a Friday.  David Turner (owner) answered my call and we agreed that he would come out at 10:00 Monday morning to take a look at the roof/siding.  Mr. Turner was punctual and got straight to business taking apart our siding trying to figure out what was causing our problem.  He told me that if for some reason he couldn't find the problem, that he would put everything back the way it was before proceeding.  We did, in fact, have what appeared to be hail damage to our siding and roofing. Mr. Turner gave us several options for how he could proceed with the work and an estimate.  We agreed on the estimate and, much to my surprise, Mr. Turner said he and the one man crew he had with him could get the house repaired by that evening.  My husband inspected the roof and siding upon completion and was satisfied that they had done exactly what they had indicated in their estimate.  Mr. Turner worked neatly during the job and cleaned up his equipment and other scraps VERY well after the job was done.  At the end of his work, he even offered to clean fingerprints left on the new siding during installation.  Upon request, he also attempted to fix a siding problem in the back of our home after the roofing job was completed, but not having any additional siding material, he was unable to correct the problem.  He DID put everything back in place as it was. My husband and I were very pleased with his professionalism and work ethic and would be happy to recommend him and use his services again in the future.

FAQs for thermostat installation and replacement projects in Nassau, NY

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
